OHBM 2026: Multiscale brain network alterations in early neurodevelopmental conditions — is autism just one thing?
OHBM 2026: Multiscale brain network alterations in early neurodevelopmental conditions — is autism just one thing?
OHBM 2026 brings a very important theme for anyone who wants to think about development without falling into overly rigid models: Multiscale brain network alterations in early neurodevelopmental conditions. Within this session, topics include Functional synchronization profiles in autism differ by spatial scale and along cortical gradients, Population-scale lifespan brain charts identify distinct clinical–biological subtypes of autism, and A Multi-Cohort, Multi-Modal Validation of Cerebello-Cortical Connectivity in Autism. That set of titles alone already signals an important shift: autism is not being treated as one single, homogeneous, easily classifiable condition.
This adds real value. For a long time, science risked speaking about “autism” as if it referred to one body, one developmental trajectory, and one brain organization. But OHBM 2026 itself suggests another direction: there are differences of scale, differences of profile, clinical and biological heterogeneity, and a need for validation across multiple cohorts and modalities.
In Brain Bee language, the question becomes very direct:
Does science make a mistake when it tries to place many different bodies inside a single theory of autism?
This is a strong question because it pulls the discussion out of excessive abstraction and brings it closer to something adolescents understand well: not everyone feels, perceives, regulates attention, and enters into relation with the world in the same way. Sometimes science wants to simplify too much in order to gain clarity. The problem is that, when it simplifies too much, it can also erase meaningful differences.
Here, the avatars that help most are Brainlly, Math/Hep, and APUS.
Brainlly matters because this is clearly a topic that depends on fine reading of signals and neurophysiological patterns. If OHBM is talking about functional synchronization, spatial scales, and clinical-biological subtypes, then we need a lens that respects dynamics, variability, and multimodal patterns.
Math/Hep matters because method needs protection. Heterogeneity cannot become an excuse for conceptual confusion. If different profiles exist, then the design needs to become better, clearer, and more honest. It is not enough to say, “it is complex.” We need to ask: at what level does it vary? In attention? In sensory integration? In synchrony? In adaptation to the environment? In social context?
APUS matters because development is never only brain network organization. It is also body in space, response to environment, rhythm, predictability, overload, comfort, movement, and the possibility of exploring the world without collapse. When the theme is autism, this becomes especially important. Not every difference appears first as “cognition.” Many differences appear first as a relation between body and territory.
The decolonial critique here can be simple and useful: sometimes science becomes crystallized when it tries to force a single category onto many ways of existing. That does not improve rigor. It reduces the phenomenon. And OHBM 2026 itself, by using terms such as clinical–biological subtypes and spatial scale, already suggests that the more fertile path may be to move beyond a single model.
A better question, then, would be this:
Which differences actually matter when we observe attention, synchrony, regulation, and relation to the environment in autistic people?
That is a good question for OHBM 2026, a good question for Brain Bee, and a very important question for Latin America. Because here we also need a science that does not only classify, but learns how to observe better.
A Brain Bee proposal for an EEG + NIRS experiment
The proposal can be short and strong: use brief naturalistic videos and social interactions, instead of relying only on highly artificial and oversimplified tasks. With EEG, we can observe attention, variability, and synchronization. With NIRS, we can track frontal response and regulation during interaction. The focus would not be only on group averages, but on seeing how different profiles appear in distinct response patterns.
The central hypothesis is direct: perhaps the problem is not only in the participants, but also in the model that tries to reduce them to a single form of organization. If EEG and NIRS capture stable differences in attention, synchrony, and response to the environment, then we move toward a neuroscience that is more sensitive to the real diversity of development.
Where OHBM 2026 is already pointing in this direction
This blog comes directly from the official program. The session Multiscale brain network alterations in early neurodevelopmental conditions is scheduled as an oral session at OHBM 2026, and the titles already make it clear that the focus is not a simplified autism model, but a field where scale, synchronization, connectivity, and subtypes all matter.
This matters because it shifts the question. Instead of asking, “what is the biomarker of autism?”, the discussion becomes more mature: what kinds of functional organization appear across different profiles, and how do those differences change with scale, context, and method?
Why this matters for Latin America
In our region, a more honest reading of autism needs to be careful not to repeat imported models as if they were universal. That does not mean rejecting international science. It means asking better questions. It means remembering that diagnosis, school context, language, sensory life, family support, and living conditions all strongly shape how each developmental trajectory appears.
This is especially important for young people between 14 and 17 years old. They can already understand that not every difference should be treated as defect, and that good science is not the one that forces everyone into a single mold, but the one that learns how to observe with greater precision.
The beauty of this OHBM 2026 theme is exactly that: it already opens space to break overly rigid models. Our role is to widen that opening.
Instead of asking only “what is the mark of autism?”, we can ask:
Which differences in attention and synchrony really matter?
What changes when we look at the body in context, instead of only the brain in abstraction?
Could some scientific errors come from the desire to simplify too much?
When neuroscience begins to measure that, it stops being only a science of fixed categories and starts becoming a science of lived differences.
